Answer:
4x + 1
Step-by-step explanation:
Multiply f + g by x because f + g is in parenthesis:
f(x) + g(x)
Then implement equation #1 for f(x) into our equation:
3x - 1 + g(x)
Then implement the other equation for g(x) into our equation:
3x - 1 + x + 2
Then switch the positions of -1 and +x:
3x + x - 1 + 2
Simmplify:
4x + 1

Answer:
b = 7.5
Step-by-step explanation:
- b × 2 = - 5 × 3
- 2b = - 15
- 2b ÷ - 2 = - 15 ÷ - 2
b = 7.5
Using function concepts, we have that:
- The independent quantity is the time.
- The dependent quantity is the volume.
- Graph H fits this problem.
<h3>What is the relation between a function and the dependent and independent variables?</h3>
A function has the following format: y = f(x).
In which each value of <u>y is a function of one value of x</u>, and thus, x is the independent variable and y is the dependent variable.
That is, the input of the function is the independent variable and the output is the dependent variable.
For this problem, the <u>volume is a function of time</u>, hence Volume = f(Time) and:
- The independent quantity is the time.
- The dependent quantity is the volume.
The <u>decay rate is constant</u>, meaning that we have a <u>decreasing linear function</u>, and graph H fits this problem.
